HiI need to update k300i. I downloaded UpdateService_Inst_2.2.13.7b.exe from their support service and run the app (BTW i have RS 236 cable) and it shows that only DSS-25 & DCU-60 are supported.As you may know DCU-60 is not supported by K300i and DSS-25 is not available in India, but here DCU-11 is available.

Guys,what does this flash things do? Does it make the phone better or what? I want to buy W550,does it need flashing too? And what's the effect if i'm doing it wrong? Does it gonna crash and i need to buy new phone?
